Mercedes to face FIA over “secret tyre test” with Pirelli

Mercedes have been referred to the FIA by the Monaco Grand Prix stewards, over a secret test of Pirelli tyres after the Spanish Grand Prix.

It is understood that Mercedes applied for permission to the FIA for the test, but were granted the approval on condition that the Pirelli test car was used. However, it has emerged that Mercedes had ran their own car during the test, which would have granted the team an unfair advantage.

Ferrari and Red Bull have protested the test, and are clearly to gain if Mercedes face sanction for running their own car.

However, it should be noted that the result of the Monaco Grand Prix will stand regardless of any action by the FIA.
